Abstract
The automobile bumper with active anticollision gas bag protection function includes a front bumper, a back bumper, a front gas bag, a back gas bag to avoid back collision, a detector, a gas trigger and an air storing cylinder. After the automobile has its speed reaching 50 km/hr, the automobile rotation speed pulse signal will enter to the control module and the control circuit will operate automatically. In sudden accident, the brake pedal is stepped to limit; and when the detector detects obstacle within 3 m, the control module will output a voltage to blow out the gas trigger and generated high pressure inert gas is filled into the gas bag for buffering and protecting the person and the automobile.
Description
The novel initiatively intelligent protection device of automobile that relates to of the present invention; in background technology; the safe automobile air bag of selling on the market has weak point: the airbag-releasing mode has only when automobile bumps against object could passive open; it is installed on the automotive interior bearing circle and the front row, side, and people, object, the car body three who is collided do not possessed protective effect.Continuous increase along with automobile quantity, the people more and more pay attention to the safety facilities performance demands when choosing automobile, annual number of dying because of traffic accident is in continuous increase, brought very big loss to the people's lives and property, initiatively the anti-collision air bag device is very urgent so develop a kind of later-model automotive safety.
The objective of the invention is: solve vehicle and under steam people and vehicle and object are played the protective effect of buffering suction, reduce personal casualty, the damage rate of object and vehicle.
The later-model technical scheme of the present invention is as follows:
Have initiatively anti-collision air bag protection function Federal bumper, mainly comprise five parts composition: front bumper (5) and rear bumper (13), preceding air bag (1) and rear gasbag (2), detector (17), gas binary pair (30) and circuit control (Figure 13) part are formed.Preceding air bag (1) and rear gasbag (2) with gas binary pair (30) are installed in respectively in the air bag supply chamber (24), bolt of rear end plate and gas cap (20) are by pad (18) in the fixation balloon, air bag supply chamber (24) shell, outer bolt pad (25) and nuts (26) connect as one, the folding compacting of preceding air bag (1) and rear gasbag (2) is packed in the air bag supply chamber (24), air bag supply chamber buckle (15) and rear gasbag supply chamber buckle (64) are contained in the front bumper (5) of car body and the bumper/spoiler and the hull bottom plate connecting bore (33) of rear bumper (13) before covering, bumper/spoiler is connected one with car body connecting bore (21).Automobile under steam, the speed of a motor vehicle reaches 50km/h when above, circuit control system is worked automatically, (the NB215 module is by the brilliant Microtronics A/S in river in Zhejiang Province, Ningbo Development and Production to 5 pin voltage signals of NB215 module, the 5 pin input voltages of this module are directly proportional with automobile rotational speed), form comparator circuit through IC1, follow the 2 pin reference voltages of IC1 to compare, IC circuit 1 and W3 can be car speed frequency pulse signal sets at 50km/h, and 3 pin of IC1 make U2 work and conducting by D3.When burst accident, the brake pedal limit of stepping on can be pressed on the brake pedal switch (3), when the speed of a motor vehicle is lower than 50km/h, triggers NE555 and delay time 1-2 second by D6, BG3, the speed of a motor vehicle is lower than below the 30km/h, the 3 pin output low levels of NE555, not conducting of U3, ignition tube (60) does not detonate; Brake back speed is when 30km/h is above; the 3 pin output high level of NE555; the U3 conducting; the distance of detector (17) detecting obstacles object distance before car is in the time of 3 meters; through T6114 inside modules data handing (the T6114 module is by the poly-precious electronic development production of Shenzhen gold); 4 pin and 5 pin input low voltage level by T6114; through D1; D2; BG1; R5 makes U1; U2; U3 conducting simultaneously; 12 volts of electric currents are through K1-1; K3-1 contact fire point fire tube (60); light gas binary pair (30); detonate base plate (55) and get through induction opening catch 1 (62) of the plug of getting through air pressure plug and gunpowder supply chamber (58); induction opening catch 2 (63); make the high-pressure inert gas in the gaholder (35) pour air bag; air bag is expanded rapidly; air bag supply chamber buckle (15) and rear gasbag supply chamber buckle (64) before releasing; at front bumper (5) and the anterior big gas bag of inflation that forms of rear bumper (13), to the driver; the pedestrian; vehicle and object play buffer protection function.
